Consider the following scenario:

• In Microsoft SQL Server 2005, Microsoft SQL Server 2008, or Microsoft SQL Server 2008 R2, you configure a peer-to-peer transactional replication that includes multiple publications in a database.
• You batch insert lots of rows into the tables that belong to these publications.

In this scenario, the latency is high for all the peer-to-peer distribution agents.

A lock is obtained in the sys.sp_MSgetpeerlsns stored procedure. This stored procedure explicitly requests an exclusive ROWLOCK table hint on a table. Although a row lock is requested, all the other distribution agents are still blocked because they are requesting the same keylock ID.

Note The sp_lock stored procedure can be used to show that all agents are waiting for the same keylock.
